The project
In Switzerland, you can borrow a soil microphone and listen to the living soil for yourself! Explore the incredible diversity of soil sounds from around the world with our interactive sound map.
Whether you’re a teacher, parent, or nature enthusiast, Sounding Soil offers engaging educational materials and excursions that let children, young people, and adults discover soil’s ecosystem firsthand—identifying soil creatures and gaining valuable insights into this critical resource.
By tuning in to the sounds of the earth, we can spark a deeper understanding of the crucial role soil plays in our food systems, our environment, and our future. Healthy soils are key to solving global challenges, from food security to climate change, and achieving the UN’s Sustainable Development Goals. Together, we can nurture the ground beneath us for a more sustainable tomorrow!
Background Knowledge
Soil: The Foundation of Life
Soil is more than just dirt—it’s the living, breathing foundation of life on Earth. This vital top layer of the Earth’s crust can range from just a few centimeters to several meters deep. Incredibly, it takes 10,000 to 20,000 years to form just 1 meter of soil! Each year, only about 0.1 mm of new soil is created in our regions. This thin layer, rich in nutrients, is called humus, and it comes from the decomposition of plants—a process made possible by billions of hardworking soil organisms.
The Hidden Orchestra Beneath Our Feet
Through Sounding Soil, we can actually hear some of these creatures in action! From the tiny springtails and mites to centipedes, beetles, earthworms, and even grasshoppers and cicadas—all of these soil animals create fascinating sounds. Whether they’re burrowing through the soil, feeding, or even communicating, the soil is alive with activity.
Each creature has its own unique sound based on its size, body structure, and behavior. The more diverse the sounds you hear in a recording, the richer the variety of life hidden beneath the surface. By listening to this hidden orchestra, we can appreciate the complexity and importance of healthy soil – and understand why protecting it is so crucial for the future of our planet.
